NAOMI / Triforce / Chihiro Netboot Security PIC Source Code

idc · Mar 2, 2016

Just going to leave this here. It's good for PIC16F628A chips.

Code:

; NAOMI/Triforce/Chihiro Netboot Security PIC v2.2
; invzim, idc/Team Avalaunch and others.

; Differences between games are the answers to:
;         AIJYOANSWER (net/non-net), AKEYCODE, BKEYCODE, FIRSTREADFILE0
;   Line: 937,                       992,      1003,     1015

This works for all revisions or just type 1 Chihiro and Triforce?

Good question. Theoretically I believe it should work on all, but I've never owned any Chihiro or Triforce kit so I've been unable to test myself.

People are encouraged to test and report back.

Mitsurugi-w · Mar 2, 2016

I'll test it. I have Type 3 for both Triforce and Chihiro set up now.

Did you ever find out if this code works for the later revisions of Triforce/Chihiro?

Thanks

Quick question:

Does it work for naomi 2 CF setups?

I'm fairly certain for compact flash you need to change at least one thing (maybe more). At the least, unless I'm completely mistaken, you need to move the comment (

from line 937 to 938 so that GD-ROM boot is set instead of network boot.

Mitsurugi-w · May 3, 2016

I did not test yet.

Usually the same zero key works for both Netboot and CF use.

That's odd, I was under the impression the CF chip needed to be different.

It is easy to use an invalid PIC for netboot on NAOMI, if you leave the python script running you'll never know if your PIC is bad because it functions the same as no PIC. The only real way to know your PIC is good for netboot is to disconnect and ensure the game keeps running.

cf is treated as gdrom, netboot is diffent by the aijyo!? answer.

there is excess padding on the des key this wouldnt work properly

if you plug in the des key and switch it to gdrom it will error 33 for whatever game you making a key for. this is how i tested mine when i posted the changes needed on the other site

that sucks... I'll need a different key for my cf setup

werejag · May 3, 2016

yeah you need two

idc · May 3, 2016

I have used this PIC for both CF (unencrypted) and netboot on NAOMI 2 with no issues.

really?

idc · May 3, 2016

Setting the dips to GD-ROM mode on the net DIMM should be enough to use unencrypted CF card-based games with a netboot chip. Both the chip and the CF card bootstrap (or "1stread.bin" in Dreamcast parlance) must be "ABC.BIN".

Mitsurugi-w · May 3, 2016

I have not tried this one because I'm not sure how to compile it, embarrassingly. But the current zero key I use and sell works perfectly fine for CF, Netboot, and Piforce. Only one needed for all uses on Naomi.

skate323k137 · May 3, 2016

Great to hear. One of those times I'm OK with being wrong

Mitsurugi-w if you need one compiled let me know. It's not too bad with mplab, but I could compile this one and send you the hex if you want. (or, idc, if you are worried about hosting the hex I have a server I could host it on for you where I keep PVM manuals).

Mitsurugi-w · May 3, 2016

That would be awesome. I downloaded mplab but never learned how to use it since most things were already compiled when I received it.

skate323k137 · May 3, 2016

No worries, I'll compile (and write/test) when I get home. Assuming it works OK I'll send you a link to the .hex file.

Mitsurugi-w · May 3, 2016

Thx bro.
